Note: Tag protection rules are currently in beta and subject to change.
When you add a tag protection rule, all tags that match the pattern provided will be protected. Only users with admin or maintain permissions, or custom roles with the "edit repository rules" permission in the repository will be able to create protected tags, and only users with admin permissions or custom roles with the "edit repository rules" permission in the repository will be able to delete protected tags. For more information, see "Repository roles for an organization." GitHub Apps require the Repository administration: write permission to modify a protected tag.
Additionally, you can create custom repository roles to allow other groups of users to create or delete tags that match tag protection rules. For more information, see "Managing custom repository roles for an organization."
